Specification of Letters Patent.

Patented Apr. 11 1916.

Application filed November 27, 1914. Serial No. 874,275.

will whom it may concern:

Be it known that I, JOHN Bn'rrxomc, a

tizen of the United States, residing at San ntonio, in the county of Bexar and State Of exas, have invented new and. useful Imrovements in Clocks, of which the followg is a specification. 1

This invention relates to clocks and more irticularly to alarm clocks.

The principal object of the invention is providea clock embodying mechanism )operating with the ordinary alarm mechaism to sound a distinctive alarm when the .ock runs down.

' Another object of the invention is to proide a novel type of alarm mechanism emodying in part a shiftable two-tone bell l'ith mechanism for shifting the bell so that he clapper will strike the independently )ned parts substantially alternately.

Another object of the invention is to;proide a clock having an alarm mechanism aranged to operate independently toned bells chen the alaim is desired to be sounded and give a distinctive alarm when the clock 'ccomes unwound.

Still another objcctof the invention is to )rovide a clock of this character embodying )ell shifting mechanism and also mechanism vhich controls the operation of thealarm ind simultaneously renders the bell shifting nechanism inoperative.

Further objects of the invention will ap- )ear as the following description is read in :onnection with the-accompanying drawing,

which forms a part of .n which Figure 1 is a face view. Fig. 2 is a similar view with the casing and dial supportin ring removed. Fig. 3 is a similarview wit the auxiliary frame plate removed. Fig. a is a side elevation with the casing removed. Fig. 5 is a top plan view of the parts shown in Fig. 4. Fig, 6 is a detail rear elevation with the casing removed. Fig. 7 is a diagrammatic elevation showing the position of the mechanism for controlling the operation of the bell shifting mechanism when about to be actuated. Fig. 8 is a similar view showing the parts in actuated position. Figs. 9, and 11 are detail sectional views all taken on the line 9-9 of Fig. 2 and showing the different positions of the alarm controlling mechanism. Fig. 12 is a detail vertical section showing the method of mountthis application, and

ing the bells. Fig. 13 is detail 1... view. of the controlling lever.

Referring more particularly to the drawing, the clock frame embodies, as is aisual,

front and rear plates 1-and2 which areconnected .together bythe corner posts 3, 4, 5 and 6, the former of which has securedthereto one v terminal, of .the :mainspring I, the opposite terminal of which is conneetedto the arbor 8 of what is commonly; known as the great wheelf. 9.; This great wheel.v 9 meshes, as is usual, with the pinion 10 of the mmutearbor 11 which carries the minute hand 12 and is connected through the gear. 13 to the escap ementtrain commongto all clocks of thischaractcr. The minute arbor l1 has seeured thereto a gear 14 ,which meshes Wltll aisomewhat larger gear-l5 on a stub shaft 16 and which has integrally formed therewith a pinion 17 inmesh with the camgear 18 having the cam sleeved!) arranged thereon so as to surround thoalarm settingsta if. 20, provided, as isz usual,- withthe setting head-or, knob 21. The stafl 20.

has keyedthereto. a disk 22 provided with a lateral finger 23 arranged to rest upon-the cam sleeve 19. .The gear 18 and the cam sleeve 19 have a normal tendency to move outwardly under the action of the leaf spring 24, but are held against.moveme nt by the lateral finger 23- resting upon the top of the sleeve 19. The pinion 17 meshes with a gear 17 secured upon the arbor 17 to which the hour hand 17 is secured.

Journaled in the frame plates below the corner post 4 is the alarm spring arbor 26 which has connected thereto its actuating spring 27, the opposite terminal of which is,

connected to the corner post 4. -The shaft 26 carries the usual winding mechanism including the loosely mounted gear 28 which meshes with the pinion '..-.29 on a counter shaft 30.. This counter shaft carries a gear 31 which is engaged with the pinion 32 on the star wheel arbor 33. This arbor 33 carries the usual star wheel 34 which actuates the pallets 35 secured to the clapper shaft 36 carrying the usual clapper rod and clapper 37. Secured to the clapper shaft 36 is an arm 38 arranged to reciprocate when the star wheel is actuated, as is usual, and which is engaged to hold the parts against actuation by the lateral extension of a controlling finger 39 secured to a. spring 40 which rests upon the gear 18 having an aperture to permit the passage of the setting staff 20. This spring acts in opposition to the spring 24 so that when the cam sleeve 19 is held depressed by the finger 23 the extension 39 will be projected into the path of the arm 38 and the alarm will be held inactive. As the wheel 18 rotates, however, and brings the shoulder on the cam sleeve around to the finger 23 which has been set by the staff 20 the sleeve will drop off of the finger and the gear 18 will be projected by the spring 24 so as to carry the extension 39 out of the path of the arm 38, thus allowing the star wheel 34 to operate upon the pallets 35 of the clapper shaft.

The casing which surrounds the frame of the clock is provided with a vertical post 42 upon which a tubular bell post is slidably mounted. Thistubular bell post carries permanently spaced bells 43 and 44 having distinctive tones when struck by the clapper. The clapper passes through a slot in the lower bell 44 and the bells are held against rotation upon the vertical post by a guiding rod 45 secured to the post 42 and extending through an aperture in the upper bell 43. In order that the bells 43 and 44 maybe raised and lowered to permit of the clapper 37 alternately engaging them there is journaled in-the frame pieces 1 and 2 a rock shaft 46 having a laterally extended arm 47 arranged to be actuated by a star wheel 48 secured to theshaft 30. The rock shaft is provided with an arm 49 having a bent outer end to engage beneath the lower bell 44 so that when the shaft 46 is rocked m the operation of the alarm the arm 49 will be raised and lowered, thereby elevating the bells 43 and 44 and permitting their depression by gravity.

The shaft 26 has secured to its forward end a pinion 50 which meshes with a gear 51 mounted upon a counter shaft 52 jour naled in the frame piece 1 and in the auxiliary frame piece 53 which is secured to the frame piece 1 by the corner posts 54. The shaft 52 projects through the 'dial 55 and carries a hand 56 operating over a graduated circle 57 supplied with the words On and Off. When the alarm has been sounded the hand 56 will point to the word Off and after being wound up the hand 56 will point to the word"On.

Secured to the outer end of the arbor 8 is a pinion 58 which meshes with a pinion of slightly larger diameter 59 secured u on the counter shaft 60 which is journale in the frame piece 1 and in the auxiliary frame piece 53. This shaft is provided with screw threads throughout the greater portion of its length and threaded thereon is a collar 61 having a lateral arm 62 slidably mounted upon a locating pin 63 which prevents rotation of the collar. This collar is arranged to engage thespring 40, which is apertured as shown in Figs. 9, 10 and 11 to permit t1 passage of the shaft 60, and to move t1 free end of the spring outwardly so as carry the extension 39 out of the path 7 the arm 38.

It will be noticed from the foregoir description that when the arbor 8 turned to wind up the main spring 7 th: the gear 58 will be rotated in a direction 1 cause the collar 61 to be moved inward] upon the shaft 60, thereby releasing tli spring 40 and permitting the same to mov inwardly into engagement with the gear 1! As the shaft 8 is rotated in the opposit direction the collar will be gradually move outwardly upon the shaft 60 until it i brought into engagement with the sprin; 40. From thence on the spring 40 will bmoved outwardly until the extension 39 i moved out of the path of the arm 38 whicl will then permit the operation of the alarm In order that the.condition of the mair spring may be ascertained from an inspection of the dial the shaft 60 has securec thereto a pinion 64 which meshes with a gear 65 secured to a counter shaft 66 journaled in the frame piece 1 and in the auxiliary .frame piece 53 and carr ing a hand 67 operating over a graduated circle 68 at the left hand side of the dial. The gear 65 has a laterally projecting, eccentrically positioned pin 69 which when the main spring is wound up is in the position shown inFig. 7. Upon rotation of the gear 65, in the direction of the arrow, the pin is brought into engagement with the vertical ,leg of a bell crank lever 70 pivotedto the frame piece 1 and having its horizontal leg slotted to receive the pin 71 connected to a rock lever 72 also pivoted to the main frame. This rock lever has its opposite end ar ranged in the path of an angular finger 73 secured to the rock shaft 46. It will thus be seen that when the pin 69 engages and moves the bell crank lever 70 that the free end of the rock lever 72 will be elevated and brought into enga ement with the finger 73, thus elevating t e arm 47 out of the path of the. star wheel 48 and at the same time lifting the bells through the arm 49 so that the clapper will only engage the lower bell 44. Simultaneously with the action just described the collar 61 will force thefspring 40 outwardly and release'the extension 39 from the finger or arm 38. In 3 this manner it will be seen that not only is an alarm sounded when the main spring is unwound but that an alarm distinctive from the ordinary alarm is sounded, thus indicating immediately that the clock needs winding, and upon inspection of the dial this can be readily seen from the position of the hands 67. If the alarm is wound up the alarm will operate in the ordinary manner, the extension 39 being carried out of 1 sprung over the end of a'a-od 75 secured to the horizontal leg of t 1 ii crank 70. This rod passes up throng. a sieeve 76 carried by the casing and when depressed by the lever acts to raise the free end of the rock lever and thereby the bells so that the clapper will only engage the lower one.

What is claimed is 1. In a clock, a gear train, a driven shaft operativcly connected with the gear train, an alarm'mechanism, means for actuating the same, means for controlling the operation of the alarm mechanism, and means actuated by the driving shaft and forming an auxiliary means for controlling the operation of the alarm mechanism.

2, In a clock, alarm mechanism including a two-tone bell and a clapper, means actuated in the operationof the alarm mecha-' nism to cause the clapper to sound both tones, and means actuated upon the running down of the clock to cause the clapper to sound only one tone.

3. In an alarm clock, vertically movable bells, reciprocating means for actuating the bells, and means to substantially alternately strike said bells and means to hold one of the bells in a position in which it is inactive.

4. In an alarm clock, vertically movable bells, reciprocating means for actuating the bells, means to substantially alternately strike said bells, and means to hold one of the bells out of the path of the striking means. i

In an alarm clock, vertically movable bells, a clapper moving in a constant path, means to alternately bring said bells into the path of the clapper and means to hold one bell in a position in which it is inactive.

6. In ad alarm clock, vertically movable bells, rcciprocating means tor-actuating said bells, means to substantially alternately strike said bells, and means to hold one bell out of the path of the striking means, said means being also adapted to stop the actuation of the striking means.

7. In an alarm clock, a Winding shaft, vertically movable hells, an alarmmechanism including the clapper reciprocating in a constant path, means to cause substantially alternate engagement of the bells by the clapper, means for holding the alarm mechanism inactive, and means actuated in the unwinding of the winding shaft to simultaneously release said holding means and move one of the bells out of the path of the clock.

8. In an alarm clock, a winding shaft, vertically movable bells, an alarm mechanism including a bell striking member; means to actuate the bells to cause substantial alternate engagement of the same by the striking member, means for holding the alarm mechanism inactive, means for releasmg said holding means at a predetermined time, and auxiliary means operated in the unwinding of the winding shaft for releasing the holding means and simultaneously moving one of the bells out of'the path of the clapper when in another position.

9. In an alarm clock, a Winding shaft, vertically movable bells, an alarm mocha-- nism including a bell striking member, means to actuate the bells to cause substantial alternate engagement of the same by the striking member, means for holding the alarm mechanism inactive, means for releas ing said holding means at a predetermined time, an auxiliary means operated in the unwinding of the winding shaft for releasing the holding means, and simultaneously moving one of the bells out of the path of the clapper, and independent means for permanently holding one of the bells out of the a path of the clapper, said independent means being arranged so that it may be moved into the path of the clapper.

In testimony whereof I afiix my signature in presence of two witnesses.
